PROTECTlNG-MANTLE FOR CYCLE OR AIR 'liIJBES.

SPECIFICATION forming part of Letters Patent No. 744,574, dated November 17, 1903.

Application filed June 4, 1903. Serial No. 160,096. (No model.)

T0 at whom it may concern.-

Be it known that I, CHRISTIAN AUGUST LEsKE, merchant, a citizen of the German Empire, and aresident of Heldburg, in the Duchy of SaXe-Meiningen, German Empire, have invented certain new and useful Improvements in Protecting-Mantles for Cycles orAir-Tubes, of which the following is a specification.

The present invention relates to a protecting-mantle for pneumatic tires of cycles and other air-tubes of animal hide. Protectingmantles of this kind made of a suitably-prepared animal hide placed between the outer from the hide.

1 The essential feature of the present innovation is that the animal hide in a tawed state with the hair on, is put in such a manner around the pneumatic tire and between the tire and the outer mantle that the hairy side fits closely on the pneumatic tire, so that this protecting-mantle makes a tearing of the outer mantle, and especially of the pneumatic tire, almost impossible; but if the outer mantle should get damaged the animal hide prevents an extension of the rent. If the injury should penetrate deeper-namely, through the hide itselfthe hairs pressed close to the tire in all parts subject to be damaged effectivelyprotect the same.

The new arrangement is illustrated on the accompanying drawing and has many advan tages.

The outer mantle is markedwith 0. Through the mantle a being interposedthe pneumatic tire I) is slightly compressed, which aids in The insertion of the protecting-mantlea is effected by placing the same and the pneumatic tube Z) inside of the outer mantle c and by pu tting at intervals of from eight to twelve inches rings of twine around the outer mantle c, whereupon this mantle, with the mantle a and tire 5 inside, is put inside of the felly, commencing near the valve, whereby the twine is removed, one ring after the other.

That Iclaim as my invention, and desire to secure by Letters Patent of the United States,

In a tire, the combination withthe inner tube, of a mantle consisting of an animal hide in a tawed state having-the hair on one side thereof, said hair side of the hide being turned inwardly against the inner tube, substantially as described. 1

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHRISTIAN AUGUST LESKE.
